Boost headers files incorrect permissions

[zhouyan@…]

I recently updated Boost 1.57, I noticed that a few header files "parameter.hpp" and some of those in the "parameter" directory has permission 755 instead of normal 644. Why make these normal header files executable?

The easy answer is "because they're that way in git".

However, they shouldn't be.

BTW, it's not just parameter, but many libraries:

asio, assign, bimap, chrono, concept_check, foreach, fusion, gil, graph, iostreams, lambda, mpl, msm, numeric, parameter, polygon, predef, ptr_container, python, test, thread, type_traits, typeof, variant and xpressive
